Annealing restores the elasticity to overworked, hardened metals by the application of heat. Wire is annealed for further redrawing or to meet customer specifications. This process also cleans the wire by burning off any lubricant left from the wire drawing process.
Batch Annealing
Wire is placed in large furnaces. A shield is placed over the wire and the air is replaced with hydrogen to form atmosphere preventing the wire from burning or changing colors. An electric heat jacket is placed over the shield and a precise amount of required heating is administered for the proper length of time to clean and soften the metal.
Strand Annealing
To anneal small diameter wire, the wire is pulled through tubes filled with hydrogen. These tubes are surrounded by heat. From the heated tubes, the wire travels through a second set of tubes immersed in water to cool the wire. The temper of the wire is determined in this operation by the heat inside the furnace and the speed at which the wire is pulled through the tubes. The wire is taken up on spools as it exits the strand annealing furnace. Each spool is monitored to ensure that our customers receive the highest quality drawn wire possible.
